Abstract (en)
[origin: EP1698808A1] A sealing device is high quality, reduces malfunctions in forming a sealing section, and improves durability of the sealing section. In the piston member 11, a part of the outer peripheral skirt section 13 is made as a stepped section to form a part having a smaller diameter (thinner wall) than the end section of the outer peripheral skirt section 13 in the side of the multiple disc clutch 4 in the axial direction, and the end section of the elastomeric member 7 forming the sealing lip 71 is fixed to the stepped section.
